模块sql语句中,能不能加入catid/$value[catid] 这样的限制?

<!--{block name="spacenews" parameter="sql/SELECT%20catid%2Csubject%20from%20supe_spaceitems%20%0D%0Awhere%20haveattach%20%3D%200%0D%0Aorder%20by%20dateline%20desc/catid/$cat[catid]/limit/0,3/cachetime/900/cachename/list_sub_3txt/tpl/data"}--><!--列表页_子栏目_3txt-->

不行，用了SQL语句就不能用自带的取数据语句。而是直接在SQL语句中写select * from supe_spaceitems where haveattach=2 and catid=123 order by dateline DESC

恩 这个可以简单扩展一下
